A basic research for New Cocktail Orthodontic Treatment -Research for Effective mixed up treatment methods and appliances

对新型鸡尾酒正畸治疗（Edgewise矫治器、拔牙/不拔牙法及其他矫治器）256例进行了基础研究，其中ⅰ类（n=64: ext.31，非ext33）、ⅱ类（n=111: ext. 65，非ext46）、ⅲ类（n=81: ext. 47，非ext34）错牙合。我们发现如下。治疗结果表明，通过有效的联合矫治器的使用，Edgewise矫治器和额外的EOA、MPA和口腔内弹性，鸡尾酒治疗效果明显改善。除III类牙合错误外，拔牙与不拔牙相比，I类和II类牙合错误治疗效果均不显著。在青年和成人病例中，拔牙与不拔牙之间存在牙根吸收和牙龈萎缩。结果表明，采用Edgewise矫治器+拔牙法或不拔牙法+其他矫治器的New Cocktail正畸治疗可获得有效的治疗效果和安全性。

A basic research for New Cocktail Orthodontic Treatment ( Edgewise appliance, extraction/nonextraction method and other appliance ) was researched about 256 cases which were class I (n=64: ext.31 nonext33), class II (n=111: ext 65, nonext46) and class III (n=81: ext 47, nonext34) malocclusion. We found as follows.1. Treatment results showed that Cocktail treatment was able to improve by effective combined appliance use, Edgewise appliance and additional EOA, MPA and interoral elastics.2. But there was not remarkable excellent treatment results in class I and class II between extraction to nonextraction method, beside class III malocclusion.3. Root resorption and gingival recession were found between extraction and nonextraction method, in young and adult cases.The results of this investigations suggested that the use of New Cocktail orthodontic treatment, which made by Edgewise appliance+ extraction or nonextraction method + other appliances, was brought effective treatment and safety results.
